Motorcycle Rally Navigation Controller MotoButtons

This is my enclosure design for the MotoButtons project, which is available at the link below (you’ll also find a detailed guide there on how to wire everything up and get it working):

Design works with a 22 mm handlebar.

These are the changes I made compared to the original design:

Buttons: The buttons are PBS 33B M12. I recommend starting to screw in the middle one first and tightening the nut so that its side wall is vertical — otherwise, the nuts of the adjacent buttons will catch on it. 

Joystick: I attached a small 5-way Adafruit style joystick to the print using two-part adhesive. There are two caps available for the joystick — short and long. When printing the small version with TPU, I didn’t achieve satisfactory flexibility, so it doesn’t cover the entire joystick. In this version, the area around the cap and the joystick needs to be filled with silicone for sealing.

Powering: The power is supplied via a 2×0.5 mm² cable, which is connected to a small waterproof 12 V → 5 V converter.

Screws: For installing the screws, I used 8 mm long M3 brass inserts with an outer diameter of 4 mm. The screws are M3, 8 mm long, with a countersunk head. The handlebar clamp screws are M5, 16 mm, with self-locking nuts.
